Module proxy 

ToolProxy — wraps a runtime’s tool dispatch so every call passes through the effect ledger.

Adapter authors register their tools by name once, then invoke through the proxy. The proxy hashes args, mints an idempotency key, runs the tool, hashes the result, appends to the ledger, returns the result.

Structs

ToolProxy

Holds tool registrations + the ledger + the secret. Send + Sync via inner Mutex; cheap to clone().

Traits

ToolHandler

A dispatchable tool. Synchronous for the v1 proxy; the SDKs wrap this in tokio::task::spawn_blocking for async use.
